给定初值及容许误差，编制牛顿法解方程f(x) 0的通用程序。
（2）给定方程,易知其有三个根
a)由牛顿方法的局部收敛性可知存在当时，Newton迭代序列收敛于根x2*。试确定尽可能大的。
b)试取若干初始值，观察当时Newton序列的收敛性以及收敛于哪一个根。
（3）通过本上机题，你明白了什么？-Given the initial value and allowable error, the preparation of Newton method to solve the equation f (x) 0 general procedure.
(2) Given the equation, it is easy to know that it has three roots
A) The local convergence of the Newton method is known to exist. At that time, the Newton iteration sequence converges to the root x2*. Try to determine as large as possible.
B) Try some initial values to observe the convergence of the Newton sequence and the root of the convergence.
(3) Through this on the machine, you understand what?
